Verdict
The clearest difference is ads: SiteBoard at none against IOU's shown. IOU's advantage is monetization model (ad-supported vs free with in-app purchases) and ratings volume (8 vs 1). On price, rating, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. IOU sells 1 in-app purchase, starting at $9.99 per month and SiteBoard sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for IOU against 5.0 for SiteBoard. That said, the two scores are not equally well evidenced: IOU has 8 ratings behind it against 1, so its average is the more settled of the two.
IOU ships an update every 5 days, SiteBoard every 3 days. The most recent releases landed on October 14, 2026 and October 19, 2026 respectively.
